ANTISKIDDIN G DEVICE.

Specification of Letters Patent.

Patented June 1, 1909.

Application filed January 21', 1908. Serial No. 411,918.

To all whom it may concern:

Be it known that we, LOUIS J. CLERGY and HENRY MoRRow, citizens of theUnited States, residing at Belt, in the county of Cascade and State ofMontana, have invented a new and useful Antiskidding Device, of whichthe following is a specification.

This invention has relation to anti-skidd' g devices adapted to be usedupon motor vehicles and the like and it consists in the novelconstruction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to rovide a device of the characterindicated w ch may be applied to a vehicle and which may be operated bymeans of a lever for the purpose of forcing a supplemental wheel in hardcontact with the surface of the roadway which additional friction willhave a tendency to prevent the vehicle from having lateral skiddingmovement when making a turn or changingits course of direction.

The device consists primarily of a bracket adapted to be clamped to thehind axle of the vehicle and to which is pivotally attached a forkwithin which is ournaled a friction wheel having a beveled periphery. Anoperating lever is mounted upon the vehicle and is connected with thefork by means of a member which in turn is provided with a resilientelement which enables the friction wheel to pass over obstructions inthe road way without jerking the lever from its support.

Figure 1 is a side elevation of the device applied showing parts insection. Fig. 2 is an edge elevation of the bracket, fork and wheel ofthe device.

The device comprises a bracket embodying a pair of spaced ugs 1, and aclamp 2 by which the bracket is secured to the axle of the vehicle.Pivotally mounted between the lugs is the upper end of the yoke 3, thelower end of which carries a bolt 7 upon which is j ournaled a wheel 4having a beveled periphery 5, designed to engage with the surface of theroad-way behind the line passing through the point at which the tractionwheels of the vehicle engage the road-wa The yoke is actuated by alongitudinaly yieldable connecting rod, which comprises two members 7and 7, the latter of which is provided with a fork, the members 7 ofwhich are disposed between the forks of the yoke 3' and are engaged bythe bolt 7 upon which the wheel 4 is journaled. The two I members 7 and7 a are connected by a drawhead, which comprises a casing 10 and a cap13 threaded thereon. 'The outer wall 8 ol' the casing is provided withan orifice through which projects the upper end of the member 7, andupon which is arranged a coiled spring 9, one terminal of which bearsagainst the said casing wall. The other terminal of the spring bearsagainst a nut 11 carried by the inner end of the member 7 and is adjustspring. The member 7'' is also provided with a rigid stop 12 thatserves to limit its inward movement relative to the casing. The cap 13is provided with a reduced extension 14 that is furnished with athreaded orifice to be engaged by the lower end of the member 7, theupper end of which is connected with the lever 6 pivoted to the base ofa locking quadrant 15 secured to the side of the vehicle; This lever isprovided with an ordinary spring actuated hand controlled'latch 14arranged to 006 rant to hold t e wheel 4 in or ment with the ground.

From the foregoing description it is obvious that when the lever Gisforced forwardly the connecting rod is moved longitudinallv and thelower end of the fork 3 will describe an are which forcibly brings the.beveled periphery 5 of the wheel 4 in hard contact with the surface ofthe road way; Should the said wheel 4 engage an obstruction upon theroad way the spring 9 will give sufficiently in order to permit thesections of the rod to move longitudinally with relation to each otherwhich will enable the said wheel 4 to ride over such obstruction. Whenthe wheel 4 is in contact with the surface of the road way as abovedescribed the beveled periphery thereof will cut into the surface of theroad and prevent the vehicle from hav ing any tendency to skid.laterally as a result of the change in direction of travel. 7

Having described our invention, what we claim as new and desire tosecure by Letters Patent is:

The combination with the rear axle of a vehicle, of a clamp rigidlysecured thereto and provided with a pair of spaced lugs, a yoke pivotedbetween the lugs and provided at its lower end with a bolt, a sharpenedwheel journaled on the bolt, an operating lever, a locking quadrant withwhich the lever cooperates, and yieldable means connecting the lever andthe bolt comprising a out of engageable in order to regulate the tensionof the erate with the locking quadllll drew-head inolosin & coiledS)IiI1 and at I b I I panof rods, one of which has one end rigidly soured to the draw-head and its outer end pivotally connected with thelever, the other rod having one end connetedwith the said bolt and itsother end projected Within the draw head and extended through the coiledspring, and provided with a nut by which to regulate the tension of thespring, and a stop 10 carried by the last named rod to limit its linward movement relative y to the drawhead.

In testimony that we claim the foregoing v as our own, we have heretoafiixed our signal tures in the resence of two witnesses.
